For all the talk of smart homes, yours isn't really all that intelligent, is it. Time to fix that. These motion-sensing lights can make light switches unnecessary, and they're currently on sale for 57% off.

These wireless, LED lights will turn on when you move within 10 feet of their range and will turn off on their own after they don't detect any motion for about 17 seconds. Place them wherever you need to shed a little task lighting — like under cabinets, inside a closet, or even along stairs. The lights are detachable, so they're ideally suited for apartment dwellers or those who move around a lot.

These motion-sensor lights normally cost $50.99, but you can pick up a pack of 10 for $21.99 and save $29.
